Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755640, here are decompositions:

37 + 8755603 = 8755640
139 + 8755501 = 8755640
241 + 8755399 = 8755640
349 + 8755291 = 8755640
373 + 8755267 = 8755640
409 + 8755231 = 8755640
463 + 8755177 = 8755640
499 + 8755141 = 8755640

Showing the first eight; more decompositions exist.
